Lucas went on a hike up a steep mountain and discovered seashells imprinted on rocks at the top. He was puzzled about how they got there. Explain to Lucas how the seashells got there?

Multiple Choice

1.     Yousef  hypothesizes that rock can undergo weathering due to the freezing of water. To test his hypothesis, he conducts an experiment using wet plaster and two containers. In Container 2, he places a balloon filled with water, ties it, and submerges it into the wet plaster.

The next day, Yousef observes that the plaster in each container is hard and has a smooth surface. He then puts both containers into a freezer overnight.

 

Yousef removes the containers from the freezer. He compares the surfaces of the plaster in each container and observes that they look different from each other.

 

Describe an observation that would be evidence to support Yousef claim…… 

• a.    plaster with the balloon in may have cracks on the surface around the balloon and the plaster without the balloon in would not have any cracks on the surface

• a.    plaster with the balloon in may have no cracks on the surface around the balloon and the plaster without the balloon in would not have any cracks on the surface

• a.     plaster with the balloon in may have no cracks on the surface around the balloon and the plaster without the balloon in would have cracks on the surface

Multiple Choice

Explain why the plaster surfac…es look different from each other………

• They look different due to the fact that when the plaster was wet in the container with the balloon, the water was in  a solid form and not yet a liquid. When placed in the freezer, the water in the balloon became a liquid. ( taken out the freezer)When the water froze the freezing and thawing caused: contractions and the expansion in the plaster , this causing pressure and causing the surface to crack and the other to remain the same.

• They look different due to the fact that when the plaster was wet in the container with the balloon, the water was in  a liquid form and not yet a solid. When placed in the freezer, the water in the balloon became a solid. ( taken out the freezer)When the ice thawed the freezing and thawing caused: contractions and the expansion in the plaster , this causing pressure and causing the surface to crack and the other to remain the same.

Multiple Choice

Explain how freezing and thawing water causes weathering of rock in nature

• When water freezes, it expands. The ice then works as a wedge. It slowly widens the cracks and splits the rock. When ice melts, liquid water performs the act of erosion by carrying away the tiny rock fragments lost in the split.

• The rocks splits because someone broke the rock

Multiple Choice

we can learn about the past from rocks and fossils

• Fossils can tell us about changes in an environment over time. For example, the rock layers beneath a forest can contain fossils of animals that live in a water environment. The rock layers and fossils get older as we dig deeper into the ground.

• Fossils can not tell us about changes in an environment over time.

• Fossils can only tell us about animals that live in a water

Multiple Choice

• 4 legs and wings

• 4 legs and a tail

• no legs and a tail

Multiple Choice

• The fish is found in the top layer which makes it the youngest. Sedimentary rock takes many years to form. The layers at the bottom are formed first which makes them older. The layers at the top are newest which makes them younger.

• The fern is found in the top layer which makes it the youngest. Sedimentary rock takes many years to form. The layers at the bottom are formed first which makes them older. The layers at the top are newest which makes them younger.
